FIELD OF TECHNOLOGY

The following relates to the field of lighting packaging, in particularto a packaging box for an illumination source.

BACKGROUND

At present, as the fourth generation of illumination source, LED bulblamp has the characteristics of such as energy saving, environmentalprotection, long life, and small size, and is favored by consumers andis gradually replacing the traditional light source. A good packagingdesign of bulb lamp can avoid the damage caused by vibration duringtransportation. In the conventional art, to avoid damage, a packagingdesign with a number of liners is often used, that is, a lining body isarranged in a tetrahedron box, and a head of a lamp is jammed in thehole of the lining body (a lining body to hold the bulb portion may alsobe provided), thus preventing the bulb lamp from shaking in thepackaging box during transport. The hexahedron box is the same as thecommon packaging box, and the bulb lamps are placed in a space enclosedby six cardboards of the box, one of the cardboards (or two oppositecardboards) can be flipped open to pick and place the bulb lamps.Although the bulb packaging design in the conventional art can preventthe product from shaking in the packaging box, the hexahedron box andthe use of the liners makes the number of the overall productionmaterial of the packaging box large, and the material cost is high. Itis not only necessary to make the box body, but also to make the liningbody, and after the completion of the production of the two, they needto be assembled together before the bulb lamps are placed. The wholeproduction and packaging process is time-consuming and laborious, theproduction process is not simple enough, and the production cost isrelatively high.

DETAILED DESCRIPTION

In the following, the present disclosure is further explained in detailcombining with the accompanying drawings and specific embodiments.

FIGS. 1 to 6 and FIGS. 10 to 11 shows a packaging box for anillumination source, the illumination source may be bulb lamp, cornlamp, halogen lamp, incandescent lamp, and the like, in the following,the technical scheme of the present disclosure is described mainly bytaking the bulb lamp as an example:

A packaging box of the present disclosure comprises an enclosure body100 having a cavity formed inside, the outer side wall of the enclosurebody 100 forms the outer side wall of the packaging box (the packagingbox is only composed of the enclosure body 100), the enclosure body 100can enclose a bulb lamp 200 in the cavity along the circumferentialdirection thereof, the inner circumferential surface of the enclosurebody 100 has at least one press-contact portion capable of abuttingagainst the bulb lamp 200, the press-contact portion can press againstand tightly hold the outer periphery of the bulb housing, so that thebulb lamp 200 can be stabilized in the cavity.

Specifically, the packaging box is composed only of the enclosure body100, and no other structural parts, and the enclosure body 100 iscomposed only of one single cardboard (the cardboard material may be 300grams of ivory board, 350 grams of ivory board, 350 grams of grey manilaboard, etc.) that bent into shape, or the enclosure body 100 may becomposed of one single plastic sheet that bent into shape, however, whencompared with the cardboard, the cost of using plastic sheet as thematerial of the enclosure body will be slightly increased. But whencompared with the conventional art, the use of cardboard or plasticsheet greatly reduces the use of raw materials and greatly simplifiesthe production process.

In this embodiment, the enclosure body 100 is composed of one singlecardboard or plastic sheet that bent to form a polygonal shape (usingregular polygon, which makes it easier to package the illuminationsources and easier to arrange and place the packaging boxes in thesubsequent box packaging operation), that is, for the formed enclosurebody 100, its inner circumferential surface extends along a straightline in the height direction of the cavity, and two end portions of thecavity are open, when compared with the existing packaging box, theopening of both ends saves the use of the cover material, and eliminatesthe manual work and process of folding the upper and lower coverscompared with the conventional art, further reducing the productioncost.

For the bulb lamp 200 with a bulb housing of a maximum outer diameter of60 mm, it is most appropriate to bend the cardboard or plastic sheetinto a regular hexagon shape (see FIG. 3 ), of course, regularquadrilateral shape (see FIG. 1 ), regular pentagon shape (see FIG. 2 ),regular heptagon shape (see FIG. 4 ), regular octagon shape (see FIG. 5) and so on can also be considered, and compared with the regularquadrilateral packaging design, in the case of equal inscribed circlediameter, the regular hexagonal packaging design has an enclosure body100 with shorter perimeter, that is, the material is used less, and inthe regular octagonal packaging design, in the case of equal inscribedcircle diameter, although the regular octagonal packaging design has anenclosure body 100 with shorter perimeter, and the material is also usedless, its single side width is narrow, which cannot meet the needs ofLOGO printing on one side, therefore, after many verificationconsiderations, a regular hexagonal shape is most appropriate for thebulb lamp 200 with a bulb housing of a maximum outer diameter of 60 mm.

In this embodiment, after the enclosure body 100 using cardboard as thematerial is bent to a regular polygonal shape, the inscribed circlediameter of its inner circumferential surface is smaller than themaximum outer diameter of the bulb housing of the bulb lamp 200, so thatthe enclosure body 100 can tightly hold the bulb housing of the bulblamp 200 after the bulb lamp 200 is placed, and for the enclosure body100 using cardboard as the material, it must be bent into a polygonalshape to effectively hold the bulb lamp 200, the inscribed circlediameter of the polygonal enclosure body 100 is less than the maximumouter diameter of the bulb housing, and when placing the bulb lamp 200into the cavity, the periphery of the polygonal enclosure body 100 canbe expanded outward, and if the enclosure body 100 is provided incylindrical shape, the periphery of the enclosure body 100 cannot beexpanded outward (or there is a very slight expansion, depending on thetype of cardboard used), so the enclosure body 100 must be bent into apolygonal shape; specifically, for the case where the maximum outerdiameter of the bulb housing of the bulb lamp 200 to be packaged is 60mm, and the enclosure body 100 uses cardboard as the material, theinscribed circle diameter of the inner circumferential surface of theenclosure body 100 should be 57 mm, that is, the difference valuebetween the inscribed circle diameter of the inner circumferentialsurface of the enclosure body 100 and the maximum outer diameter of thebulb housing is 3 mm, and the tightness of the difference of 3 mm is themost appropriate.

Of course, if the material of the enclosure body 100 is plastic sheet,according to the specific plastic material, the toughness and plasticityof the enclosure body 100 will be different, therefore, after theenclosure body 100 using plastic sheet as the material is bent into apolygon, the difference between the inscribed circle diameter of itsinner circumferential surface and the maximum outer diameter of the bulbhousing of the bulb lamp 200 may be selected according to the specificplastic material, which will not be repeated here. In addition, if thematerial of the enclosure body 100 employs plastic sheet, the enclosurebody 100 can also be curled into a cylindrical shape besides being bentto a polygon, because the plastic material has better deformability thanthe cardboard, the inner diameter of the cylindrical enclosure body 100can be slightly smaller than the maximum outer diameter of the bubblehousing, and if the enclosure body 100 of the cardboard material isprovided to be circular, the bulb lamp 200 cannot be held tightly whenthe inner diameter is too large, and the bulb lamp 200 cannot be placedin the cavity when the inner diameter is too small due to that thecardboard has no good deformability.

Further, the height of the cavity inside the enclosure body is at leastgreater than or equal to the length of one bulb lamp 200, or the heightof the cavity may be greater than or equal to the length of two bulblamps 200, or the height of the cavity may be greater than or equal tothe length of three bulb lamps 200.

When the height of the cavity is greater than or equal to the length ofone bulb lamp 200, the inner cavity of the enclosure body 100 can onlyaccommodate one bulb lamp 200 (as shown in FIG. 10 );

When the height of the cavity is greater than or equal to the length oftwo bulb lamps 200, the inner cavity of the enclosure body 100 canaccommodate two bulb lamps 200 in the length direction, the innercircumferential surface of the enclosure body 100 has two press-contactportions capable of respectively abutting against the bulb housings ofthe two bulb lamps 200, that is, the bulb lamps 200 are packaged in theform of two-pack (as shown in FIG. 11 );

When the height of the cavity is greater than or equal to the length ofthree bulb lamps 200, the inner cavity of the enclosure body 100 canaccommodate three bulb lamps 200 in the length direction, the innercircumferential surface of the enclosure body 100 has threepress-contact portions capable of respectively abutting against the bulbhousings of the three bulb lamps 200, that is, the bulb lamps 200 arepackaged in the form of three-pack.

Further, no matter the enclosure body 100 is composed of cardboard orplastic sheet, it is necessary to form a bonding portion 101 on one sideof the enclosure body 100, the bonding portion 101 may connect and fixthe two sides of the enclosure body 100 after the bending of theenclosure body 100, the difference is that when the enclosure body 100is composed of cardboard, the bonding portion 101 may be fixedlyconnected with the other side of the enclosure body 100 by glue, andwhen the enclosure body 100 is composed of plastic sheet, the bondingportion 101 may be fixedly connected with the other side of theenclosure body 100 by high-temperature hot melting.

In addition, after packaging the bulb lamp 200 with the packaging box ofthe present disclosure, batches of packaging boxes may be placed in alarger packaging case 300 for arrangement and placement, the respectivepackaging boxes can be close to each other, with no space waste (asshown in FIG. 7 ), the batches of packaging boxes may be placed in asingle layer (as shown in FIG. 8 ), may also be placed in two layers,but with the need of arranging a partition plate 301 between the twolayers to separate them (as shown in FIG. 9 ), or may be placed in morethan two layers.

In summary, the packaging box for an illumination source of the presentdisclosure is composed of one cardboard or one plastic sheet that bentinto shape, which is simpler in manufacture and greatly reduces the useof raw materials compared with the conventional art; in addition, thepackaging box stabilizes the illumination source in the cavity by theholding force of the enclosure body to the illumination source, whichcan meet International Standard ISO 2248-1985 (product drop test), andavoid the use of a package with inner liner to clamp product, whichsimplifies the production process and further reduces the use of rawmaterials, greatly reducing the production costs; due to the open designof the two end portions of the packaging box, the material consumptionof the internal cavity caused by arranging the upper and lower covers isreduced, and cancel of the upper and lower covers greatly facilitatesthe operation of placing and picking the illumination source.
